Toall whom it may concern:

Be it known that I, I-IANs CHRISTIAN BJERING, a subject of the King ofNorway,

residing at Gjovik, Norway, have invented certain new and usefulImprovements in Means for Removing Grass from Mower- Knives; and I dohereby declare thefollowing to be a full,c lear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains' to make and use the same, reference being had to theaccompanying drawlngs,

and to letters or figures of reference marked thereon, which form a partof this specification.

Thisinvention relates to; improvementsin' mowers and the particular.objectof the 111-. ventionis to provide means for prevent ng grass orthe like from accumulating on'the reciprocating knlves of theIIIOWGI'S'OI bethe same;

In the following the invention shall be described in connection with amower of the kind specified in-U. S; Letters Patent No.

1089039, issued'March 3, 1914,.to Hans Bj ering but it will be easilyunderstood that the invention is also applicable on other typesofmowers, where the grassmay tend to accumulateand stick between themowing V knives andtheir protecting fingers orany other stationary partof thev cutting majection'on said knife during the reciprocatl ingmovement of said knife to remove grass chinery; V On the drawlngs,Figure ,1 shows a vertlcal sectional view through the cutting apparatusof a mowing machine of the klnd re to the'reciprocating bearers '3, 4:.

Numeral 5 is a knife holder or frame a protecting finger'secured to saidframe vby means of bolt 7 and plate 8; 9 is thefinger extensionprotecting the under side the The particular form of the protectingfinger here shown, which does not form a part of' this invention hasbeen designed particularly with a View to avoiding the'sti'cking ofgrassin the cutting apparatus; but even with this improved constructiongrass, especially when it is wet will be liable to accumulate betweentheupper knife 2 and the finger 6, and this dead grass willthen prevent thefresh grass from getting access Copies of this patent may be obtained tothe knives. This drawback accordingto the presentinvention is avoidedbyriveting or otherwise securing on the side of the knife (the upper side)adjacent to the sta-" grass accumulatediupon the knives, where upon the.cutgrassfwill be shaken off the knives or pushed away from the same bymeans'of-the said studlO and projection llr 12 (Fig.2) represents indotted lines the 1 rivet securing the studlO to the'knife 2.7 It will beunderstood that this invention can be applied equally well onmowersjwith underlying fingers or on mowershavingonly V rammed July 18, 191

one reciprocating knife-instead of two such tween said knivesiandthe'fingers protecting knives; and-'ia'lsothe details of constructionmay be considerably varied without departing from the' spirit of theinvention. I

Claims. 1. In a mower,

reciprocableknife carried by said frame, a

stationary protecting finger carried by said frame, and extending oversaid knife, a projection secured to said knife and extending up towardsaid stationary protecting finger,

and a downwardly extending portion of said I protecting fingercooperating with theproaccumulated between said knife and said protectlng fingen,

2. In a mower, a

a knife holding frame, a

knife holding frame, a j

pair of reciprocable knives carried by said upper side of-theupperknife, and a downoperating with the "projection" on said upperknife during the reciprocation of the latter.

' frame, alstationary protecting fingerextend ing over said knives, aprojection on the wardly extending port on of said finger co- Intestimonyjthat I claim the foregoing as my invention, I have signedimyname inpresence of two subscribing witnesses.
